First steps

Setting up your database with DenoDB is a four-step process:

• Create a database, using Database (learn more about clients):

  const connection = new PostgresConnector({
    host: '...',
    username: 'user',
    password: 'password',
    database: 'airlines',
  });
  
  const db = new Database(connection);
  

• Create models, extending Model. table and fields are both required static attributes:

  class User extends Model {
    static table = 'users';
  
    static timestamps = true;
  
    static fields = {
      id: {
        primaryKey: true,
        autoIncrement: true,
      },
      name: DataTypes.STRING,
      email: {
        type: DataTypes.STRING,
        unique: true,
        allowNull: false,
        length: 50,
      },
    };
  }
  

• Link your models, to add them to your database instance:

  db.link([User]);
  

• Optional: Create tables in your database, by using sync(...):

  await db.sync();
  

• Query your models!

  await User.create({ name: 'Amelia' });
  await User.all();
  await User.deleteById('1');
